Redefining Open-Top Thrills: Is the Mercedes-AMG SL 43 the Right Roadster for You?
For over a decade, I’ve lived and breathed performance cars, and few badges carry the weight of the Mercedes-AMG SL. The latest generation, embracing the full AMG treatment, promised a return to the SL’s sporting roots. But with the stratospheric prices of the SL 55 and SL 63, a burning question arose: can a four-cylinder Mercedes-AMG SL 43 truly capture the essence of this legendary roadster? Especially now, with luxury consumers becoming more conscious of price point in 2025.
The SL’s transformation has been remarkable. What began as a purebred racer evolved into a luxurious grand tourer. The newest iteration, while still substantial in size, boasts a sharper focus on performance, marking a significant character shift. But this renewed athleticism came with a hefty price tag. The SL 55 commanded a base price north of $140,000, while the SL 63 easily exceeded $180,000.
Enter the Mercedes-AMG SL 43, positioned as the “entry-level” model, starting around $111,000. This represents a considerable saving compared to its V8-powered siblings. But the key question remains: does this price reduction come at the cost of the SL’s soul? Can a turbocharged four-cylinder engine deliver the performance and emotional connection expected from an AMG roadster?
A Deep Dive Under the Hood: The Electrified Four-Cylinder Heart
The heart of the SL 43 is undoubtedly its most talked-about feature: a 2.0-liter turbocharged inline-four. This isn’t your average four-pot; it incorporates an electric turbocharger, a technology derived from Formula 1. This innovative system utilizes a small electric motor positioned between the turbine and compressor wheels to rapidly spool up the turbo, virtually eliminating lag and providing instant throttle response.
The result is a respectable 375 horsepower and 354 pound-feet of torque. Now, some might scoff at those numbers in a car tipping the scales close to 4,000 pounds. However, this engine is a spirited overachiever, punching well above its weight class. Paired with a responsive nine-speed automatic transmission, the SL 43 delivers confident acceleration and a surprisingly engaging driving experience. While it might be down on power compared to the SL 55, most drivers wouldn’t notice the deficit in real-world driving scenarios. For many, finding a great “Mercedes-Benz dealer near me” that can highlight these performance features is key.
And let’s address the elephant in the room: the sound. While it lacks the guttural roar of the V8, the SL 43’s exhaust note is far from bland. It’s a distinctive, raspy growl that adds a layer of excitement to the driving experience, especially when the turbo is singing its song. It delivers aural drama and a sense of speed that belies its cylinder count.
Carving Corners: Agility and Balance on the Open Road
Beyond the engine, the SL 43 shines when the road gets twisty. While it doesn’t possess the all-wheel-drive system or advanced torque-vectoring capabilities of its more expensive counterparts, it retains much of the agility and balance that make the SL a rewarding sports car. The front end feels remarkably planted and eager to change direction, responding instantly to steering inputs.
The SL 43’s ability to handle challenging roads without the aid of active suspension components is particularly impressive. The traditional combination of shocks and steel springs provides a well-controlled ride that inspires confidence. It’s a testament to AMG’s engineering prowess that they were able to extract so much performance from a relatively simple setup.
Grand Touring Compromises? Comfort and Refinement in Question
However, the SL 43 stumbles in areas where a grand tourer should excel: namely, comfort and refinement. While the turbo-four engine is exciting in Sport+ mode, it struggles to settle down in Comfort mode. The engine’s high-strung nature becomes apparent at low speeds, with noticeable vibrations at stoplights. This is especially true in urban environments like driving around Los Angeles or Miami; which are popular areas to purchase Mercedes-AMG SL 43 models.
Around town, the powertrain calibration feels somewhat inconsistent. The throttle response can be abrupt, making it difficult to accelerate smoothly from a standstill. The nine-speed transmission can also be hesitant to downshift, leaving the engine feeling a step behind. This means the SL 43 lacks the dual-personality of its V8-powered siblings, excelling at high-speed thrills but falling short in everyday driving scenarios. This is something to consider if you are located in a large city, where you will be doing a lot of city driving.
Exterior Elegance and Interior Luxury: Staying True to the SL Lineage
Fortunately, the rest of the SL 43 package is as impressive as its pricier counterparts. Most of the cost savings appear to have come from under the hood, leaving the overall aesthetic and cabin layout virtually unchanged. The car boasts stunning proportions that, combined with optional larger wheels, create a visually striking presence. You’d have to be a true aficionado to notice the subtle differences in the bumpers and exhaust tips. The key is to know what kind of “Mercedes-Benz services near me” are available to you for customization.
Inside, the SL 43 features the same 12.3-inch digital instrument cluster and 11.9-inch central touchscreen as the higher-end models. The seats are comfortable and supportive, and the retractable soft top folds away in just 15 seconds at speeds up to 37 mph.
The cabin is well-isolated from wind and road noise, especially at higher speeds when the engine settles into a lower RPM range. The SL 43’s interior showcases Mercedes-Benz’s expertise in creating world-class environments, offering a luxurious and comfortable experience.
The Verdict: Bridging the Gap, with Room for Improvement
The ultimate question for anyone considering a Mercedes-AMG SL 43 is whether the price discount outweighs the trade-offs. In my opinion, the answer is a qualified yes.
Consider a well-equipped SL 43 with an as-tested price of around $120,000. That’s a significant saving compared to the SL 63, yet you still get a car that looks just as good and offers a similarly luxurious cabin. The SL 43 opens up the new SL to a broader market segment, making this iconic roadster accessible to a wider range of buyers.
However, the SL 43 isn’t without its flaws. The powertrain calibration issues need to be addressed. The engine and transmission need to be refined to provide a smoother and more responsive driving experience, especially at low speeds.
Despite these shortcomings, I wouldn’t dismiss the SL 43 based solely on its cylinder count. The inline-four engine has plenty of character and deserves its place under the SL’s hood. Once Mercedes-AMG addresses the powertrain calibration issues, the SL 43 has the potential to be a truly compelling and well-rounded roadster. It’s about finding the right “Mercedes-Benz auto repair” shop to service your vehicle.

Final Thoughts: Is the SL 43 Right for You?
The Mercedes-AMG SL 43 represents a bold move by AMG, offering a more accessible entry point into the world of high-performance roadsters.
